As a therapeutic modality, ultrasound is a form of heat treatment for soft tissue trauma to minimize swelling and pain, reduce muscle spasms, and expand the range of motion. Making high frequency sound waves, ultrasound reaches deep into a damaged area, creating heat that pulls blood into the area in order to enhance the mending process.
Ultrasound is applied softly with a handheld soundhead, using strokes or circles over the affected area. An ultrasound gel might be administered during the ultrasound therapy session. The role of an ultrasound is to expedite your healing time and alleviate your pain.
In one study, the addition of ultrasound to exercise treatment for lumbar spinal stenosis relief decreased the amount of analgesic consumption by the patients. (1)
